When preparing a site for venipunctures with alcohol, how long must the area be cleaned?
- A. 5 seconds
- B. 10 seconds
- C. 30 seconds
- D. 60 seconds
Correct Answer: C
Rationale: When preparing a site for venipunctures with alcohol, it is important to clean the area for at least 30 seconds. This ensures that the alcohol thoroughly disinfects the skin and reduces the risk of introducing infections during the procedure. Cleaning the area for a full 30 seconds allows the alcohol to effectively kill any bacteria present on the skin's surface, creating a safe environment for the venipuncture to take place. Shortening the cleaning time may compromise the cleanliness of the site and increase the chances of contamination. Therefore, 30 seconds is the recommended duration for cleaning the site with alcohol before a venipuncture.

- A. 3rd
- B. 7th
- C. 5th
- D. 8th
Correct Answer: B
Rationale: Bell's palsy is a cranial nerve disorder characterized by weakness or paralysis of the facial muscles due to inflammation, compression, or damage to the seventh cranial nerve - the facial nerve. The facial nerve controls the muscles responsible for facial expressions and functions like smiling, closing the eyes, and raising the eyebrows. Symptoms of Bell's palsy can include drooping of one side of the face, difficulty in closing one eye, drooling, impaired taste, and difficulty in smiling.
A client is admitted for postoperative assessment and recovery after surgery for a kidney tumor. The nurse needs to assess for signs of urinary tract infection. Which of the ff measures can be used to help detect UTI?
- A. Encourage the client to breathe deeply and cough every 2hrs
- B. Monitor temperature every 4hrs
- C. Splint the incision when repositioning the client
- D. Irrigate tubes as ordered CARING FOR CLIENTS WITH DISORDERS OF THE BLADDER AND URETHRA
Correct Answer: B
Rationale: Monitoring temperature every 4 hours is crucial in detecting signs of a urinary tract infection in a postoperative client. An increase in temperature can indicate the presence of an infection, and early identification is essential for prompt treatment. While coughing and deep breathing (Option A) are beneficial for postoperative clients to prevent respiratory complications, they are not directly related to detecting UTI. Splinting the incision (Option C) is important for incisional care but does not specifically help in detecting UTI. Irrigating tubes (Option D) should only be done as ordered by the healthcare provider and is not a routine measure for detecting UTI.
Fred is a 12-year-old boy diagnosed with pneumococcal pneumonia. Which of the following would Nurse Nica expect to assess?
- A. Mild cough
- B. Slight fever
- C. Chest pain
- D. Bulging fontanel
Correct Answer: C
Rationale: Pneumococcal pneumonia often presents with symptoms such as chest pain due to inflammation of the lung tissue. In children, chest pain may be a common symptom alongside other signs like fever, cough, and difficulty breathing. Since Fred has been diagnosed with pneumococcal pneumonia, Nurse Nica would expect to assess him for chest pain as part of the typical presentation of this condition in children.
The bronchospasm and dyspnea are clinical manifestation of organophosphorus poisoning are caused by :
- A. muscarinic action
- B. nicotinic action
- C. CNS action
- D. all the above
Correct Answer: A
Rationale: The bronchospasm and dyspnea seen in organophosphorus poisoning are primarily caused by the muscarinic action of the toxic substance. Organophosphates inhibit acetylcholinesterase, leading to an excess of acetylcholine at the neuromuscular junctions. This results in overstimulation of muscarinic receptors, causing symptoms such as bronchoconstriction, increased secretions, and respiratory distress. Nicotinic actions primarily lead to muscle weakness and paralysis, while CNS actions can cause seizures and altered mental status. So, in the case of bronchospasm and dyspnea, the muscarinic action is the main contributing factor.
